Default New to the sc300 NA-T world. Total timing question

Alright I'm running a dave H kit on a 96 Sc300. 2.5mm HG. No MAF. VPC and GCC.

First off I know how to set the base timing. I'm assuming you guys leave the factory 10*BTDC base timing for NA-T's?

Anyway assuming one had to use the factory computer. Is there anyway to alter WOT total timing under boost? I can't seem to find anyone that can even tell me what the total timing at WOT is on the NA 2j's? Or how to adjust it.

I know on the turbo buicks there's a box we plug into the MAF and you can adjust fuel @ idle, WOT, and timing @ idle and WOT. Anything like that for the SC300's?

Help me out here! :lol:

i don't think you can adjust the timing at WOT without an actual Standalone ECU.

i used to run around 12-13 degree of timing at Peak boost through redline. that was a conservative 91 octane tune with around 17psi (8.5:1 compression)

You can use the AEM FIC. Allows you to retard the timing but not advance.
